CAN-OPENER.

Specification of Letters Patent.

Patented April 21, 1908.

To all whom it may concern 1, Be it known that I, FRANK citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Can-Openers and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference eing had to the accom anying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in combination tools.

This invention consists of a combined can opener and bottle cap remover, which will'be fully understood by reference to the accompanying drawing in which, a

Figure '1 is a side elevation of the device; Fig. 2 is an underneath view of the same or a view looking in the direction of arrow 2 in Fig. 3 is a to plan view of the same or a view looking in t he direction of arrow 3 in Fig. 1. Fig. 4 is a central longitudinal Fig. 3 looking in the directionof the .arrow. Fig. 5 is a detail view of the slidable can 0 ening knife employed in connection with tffe device. Fig. 6 is a top view of the knife before its completion or before the bending of the portion of it over upon its body part to form a tongue which slides in a slot in the body of the tool. v

The same reference characters indicate the same parts in all the views. 7

Let the numeral 5 designate the body of the tool which consists of a plate having a longitudinal slot 6.. One extremity of this body part is reduced and bent downwardly forming a comparatively-pointed member 7 adapted to pierce the center of the can ca a portion of which is to be removed. Slida ly mounted in the slot 6 of the body of the tool, is a knife member 8 consistin of a' downate 10 and a reinforcing 1part 12 occupying a position on top of the p ate and forming a tongue adapted to slide freely in the slot 6. Ooun'tersunk in the knife member 10 and the tongue 12 is the head A of a screw whose threaded shank is designated B. This shank passes through the slot and threaded thereon is a thumb nut CANFIELD, a

C. 7 Between the thumb nut and the body of the tool is a washer D. The knife plate member 10 and the washer engage'the opposite sides of the slot while the tongue 12 is fashioned to fit the slot which forms a guide for the knife. The thumb nut when tightened locks the knife in any position of adjustment on the slotted portion of the tool body. By loosening the 'thumb nut, the

.knife may be adjusted to occupy any desired position according to the size of the can to be opened or of the radius of the are which the cutter part 9 is to describe during the cutting operation.

The extremity of the body of the tool opposite the brad 7, is provided with a slot E on opposite sides of w ich are parts F and G. The part G extends considerably beyond the point F. This extremity of the tool is adapted for removing the caps of bottles. During this operation the member F engages the edge of the ca while the outer extremity of the member (5 engages the cap on top and forms a sort of fulcrum. Then as the body of the tool is raised, the member F pulls the edge of the ca From the foregoing description the use and operation of my improved device will be readily understood and need not be further described in detail.

Having thus described my invention, what I claim is:

A can opener comprising a plate slotted intermediate its extremities, one of its extremities having a downwardly bent ointed portion ada ted to enter the canto be opened, a knife sli able in the slot and having a downwardly extending cutter, and a body art provided with a reinforcing member ent thereupon to form a tongue adapted to enter and slide in the slot of the body of the tool,

the body of the knife overlapping the slot, a

screw whose head is countersunk in the body of the knife, a thumb nut applied to the screw on the opposite side of the body of the tool, and a washer interposed between the thumb nut and the body of the tool.

In testimony whereof I in presence of two witnesses.

' FRANK CANFIELD.
